最初在数字数组中曾经是数字，它工作正常，但是当我将数字更改为图片时，我可以拖动它们，但我无法放在正确的位置，例如..它们是可拖动的，但不可拖放！ 我没有碰代码，我只是更改了数组和循环以显示图片， 请问任何人都知道该怎么做？
这是样式.css文件

该代码最初是数组中的 10 个元素，请帮助
好吧，我找到了一个答案，如果有人需要这段代码，你只需要编辑
function handleCardDrop( event, ui ) {
var slotNumber = $(this).data( 'string' );
var cardNumber = ui.draggable.data( 'string' );
这样，它将检测字符串:)有好的一天
